Ritchey
Z-Max Evolution WCS (27.5-inch)

Details

The Z-Max has been Ritchey's signature MTB tread pattern for well over a decade. The Z-Max Evolution WCS features aggressive lugs that are spaced wide and shortened for faster handling, reduced rolling resistance and lighter weight. The sticky, slow-rebound rubber compound on the sides of the tire ensures you can take fast lines on the toughest trails.

Ritchey Vector Force Analysis (VFA) optimizes each tire knob to meet the diverse directional forces encountered while cornering, braking, climbing and descending. The tread pattern (A) follows a parabolic curve for traction at every lean angle. The tread knobs (B) feature different designs to counteract the vector force applied at any given angle, providing confidence-inspiring traction in any condition.
